CS – 234. Individual Programming Assignment: #3(a). Due Date: Midnight 11/10/24
Write a Stock class. Declare the data members Symbol, volume, price as private.
It should have a constructor which requires a symbol (string), a volume (int), and a price (double). Other than the getters and setters, the following operational methods are required for the Stock class.
Method Name Parameters Purpose of the method
Buy number, new_price decreases the volume by number and sets the stock-price to the new price
Sell number, new_price increases the volume by number and sets the stock-price to the new price
toString none Returns a printable string with - volume and price, and total value of the stock
A stock is first offered to the public at a start-off stock-price. The initial offering also comes with an initial volume (or number of stocks). Every stock is identified by a stock symbol – which is a string. Then, the stock market takes over and the stock-price fluctuates with the buying and selling of the stock.
Write an application (call this class – Broker). The broker class acts as a buyer and seller of stock for ONE client. This application should
Request a symbol, an initial volume, and an initial price for a market stock from the user and create a Stock object with this information in it.
Output the current state of this Stock object.
Request the name of a client and their initial money.
Outputs the portfolio of the client - the name, the initial money held, and the number of stocks held (initially it would be 0).
Then, it presents an option to buy or sell the stock – or to quit the application. Based on user response, request the user for the volume and the price for buying or selling. Then, if the user wants to buy – the buy method is called on the stock object using the volume and price chosen by the user. The broker adjusts the client portfolio – to reflect the money available and stock held.
The above process is repeated - option to buy or sell or quit - is presented until the user chooses to quit.
The number of stocks bought cannot be more than the volume held in the stock; user cannot sell more than that which is held by the user; user cannot buy more than what the money available allows.
Finally output the current state of the Stock, and the user portfolio.
Ex: User inputs the symbol “MYSTK” initial volume as 10000, and starting price as $ 8.00.
User inputs the client name as “Iyengar” and client’s money as $ 50000.
Output of Current State:
Symbol MYSTK
Volume 10000
Price $ 8.00
Value $ 80000.00
User selects Buy
User inputs Volume 1000
Price 8.25
User selects Sell
User inputs Volume 500
Price 8.50
Output of Current State:
Symbol MYSTK
Volume 9500
Price $ 8.50
Value $ 80750.00
Stocks held by Broker:
Client Name: Iyengar
Client Money $ 46000
Symbol MYSTK
Volume 500
Price $ 8.50
Value $ 4250.00
Total Value: $ 50250.00
